Embodiment

[0035] A method for implementing screen projection of a projector, comprising a projector module, a communication module, and a central controller, wherein the projector module includes a signal receiving unit, a signal output unit, a processor, a microcontroller, a storage unit, and a projection unit. The signal receiving unit and the signal output unit are respectively connected to a processor, the processor is connected to a microcontroller, and the microcontroller is respectively connected to a projection unit and a storage unit; the projector module is connected to a communication module connected, the communication module is connected with the central controller.

[0036] as attached figure 1 As shown, the projection method of the projector is as follows:

[0037] (1) The central controller sends a projection request to the communication module, and the communication module sends the projection request to the projector module;

[0038] (2) The signal receiving unit in ...

Abstract

The invention provides a projection screen implementation method of a projector, and the method comprises the steps that: a central controller transmits a projection request to a communication module, and the communication module transmits the projection request to a projector module; a projector module receives projection request information from the central processor and returns projection permission information to the communication module, and the communication module returns the projection permission information to the central controller; the central controller receives the projection permission from the projector module and sends a file to be projected to the projector module through the communication module; and the projector module receives the projection file from the central processing unit and projects the file to be projected. Through cooperation among the projector module, the communication module and the central controller, screen projection of the projector is achieved, the communication module is wireless communication, and compared with traditional wired communication, more convenience is achieved.

Description

technical field [0001] The invention belongs to the technical field of a projection screen implementation method of a projector, and in particular relates to a screen projection implementation method of a projector. Background technique [0002] A projector is a device that projects content, such as images or videos, onto a projection screen. Projectors are used in many scenarios. For example, during a meeting, use a projector to put the text or image content involved in the meeting on the projection screen for everyone to watch; visual enjoyment. [0003] Now the projection mode of ordinary projectors generally adopts a wired connection to connect to a computer, and the information to be displayed is transmitted to the projector, but this wired connection has brought a lot of inconvenience. For example, in occasions such as conferences or lectures, when different participants take turns to speak or different speakers take turns to demonstrate, they have to frequently rec...
